Multiple data visualization with the single time graph in Code Composer Studio

Hello

I want to visualize some data which will change during time (f.e. logging ADC values or logical inputs) like as a normal oscilloscope or logic analyzer.

Therefore I use the the single time graph tool for the variables/expressions during the MCU debugging. This works for one variable/data good.
But how I could display multiple values or data in the same diagram?

I am not able to add more data with others colors.

    Hi Seb,

    Multiple variables in the same graph... I don't think this is possible. Though you can configure the dual-time graph option. Check this out:

    Hi Gautam,

    thanks i will try it with dual time graph the next few days.
    But i think this will only a little workaround. No solution yet.

    The symbol / icon of CCS single- time graph gives the impression to simple displays data (a blue and a read line) in one graph!

    Monitoring of multiple data is sometimes very important and necessary. I look towards VDHL simulations or MatLab/Simulink calculations where there is no problem to display multiple signals/data. CCS should handle this by the GUI because I think this is no MCU debuging limitation. So this will be a nice topic for a next CCS version.

    I try it further. My next idea is it to reference on arrays or structured variables in debug mode.

    I agree with you Seb! This is a limitation felt by many users... I don't have an idea what limitations developers have at their end.

    As a feedback I'll forward this to a concerned person.

    Goodluck & Regards,

    Gautam

    Hi Gautam.
    I tried the dual time graph analysis. I think that not a successfully way. It was not working in the first way.

    The best solution for multiple data is at the moment.
    - Open more single time graph an plot this in two separate graphs among each other.
    - Reduce the sampling buffer to a suitable value
    - and enable continuous sampling / refresh

    But for more as 4 my Laptop display is to small.

    That's what we all do, seb :)
